Product Details

GMD rock tools for top hammer drilling are designed to transmit intensive impact energy into the rock with the least possible loss of energy. The result is good rock breakage, high penetration rates and high productivity. This, together with optimal hole quality, great reliability and long service life, gives the best possible blasting results, outstanding drill-steel economy and low total cost.

Our products are produced from premium steels and fitted with tips with high quality tungsten carbide. It could ensure maximum service life and impact strength.

Suitable for powerful percussive drills and top hammers with high speed drifter, such as Atlas Copco 282 rocket boomer, Atlas Copco 352 rocket boomer jumbo, Atlas Copco D7roc, Furukawa HCR 1200, Tamrock, and Ingesoll Rand ECM660.

Packing Picture:  

Choosing The Right Carbide

The larger the volume of the Carbide, the more aggressive the Bit. The more aggressive Carbides assist movement of the chips away from the face as there is more room for airflow on the face of the Bit. These more aggressive Bits help to break out larger chips, which increases the penetration rate. The greater volume of Carbide can lead to longer Bit life.


Button Shape

Application

Spherical

Spherical Carbides for use in medium to hard rock, with fractured or seamy applications.

Semi-ballistic

Semi-ballistic shaped, more aggressive than the Spherical Carbides, for soft to medium consistent rock.

Ballistic

Bullet shaped, very aggressive fast penetration in soft to medium consistent rock.
